Get Driving -> Active Safety Brake (with IEBA and Collision Risk Alert) Guide for Citroen C3 Aircross SUV Second Generation (2024-2026)

Driving

►ꢀ Release the accelerator pedal.

Prolonged pressing and holding

upwards/downwards on 3 causes a

very rapid change in vehicle speed.

This system:

– warns the driver that their vehicle is at

risk of collision with the preceding vehicle, a

pedestrian or a cyclist.

– reduces the vehicle's speed to avoid a

collision or to limit its severity.

As a precaution, we recommend

setting a cruise speed fairly close to

the current speed of your vehicle, to avoid

any sudden acceleration or deceleration of

the vehicle.

►ꢀ Pressing button 2-II> temporarily pauses the

function.

►ꢀ Pressing button 2-II> or one of the buttons

3-SET again resumes operation of the cruise

control at the previously saved speed setting.

The system also takes motorcyclists

into account.

It may also react on animals. Animals

(especially animals smaller than 0.5 m) and

objects on the road are not necessarily

detected.

Cruise control operation can also be

interrupted temporarily:

– by pressing the brake pedal.

– by depressing the clutch pedal for more

5 seconds (manual gearbox).

– by shifting to neutral or engaging reverse

gear.

– automatically, if the electronic stability

control (ESC) system is triggered.

Off

►ꢀ Press 1-MODE: the cruise control

information display disappears.

Malfunction

In the event of a malfunction, dashes are

displayed flashing and then fixed instead of the

Driving

This system does not replace the need

for driver vigilance.

This system is designed to assist the driver

and improve road safety.

the system via the vehicle's configuration menu

is recommended, for instance:

– Towing a trailer (particularly a trailer without

its own braking system).

– Front camera out of regular position or

missing cover.

– Brake discs cooling process is on-going.

– In curves.

It is the driver's responsibility to continuously

monitor traffic conditions in accordance

with applicable driving regulations.

– Carrying long objects on roof bars.

– Driving with snow chains.

– Using an automatic car wash.

– Performing any maintenance (e.g. changing

a wheel, working inside the engine

compartment).

– Placing the vehicle on a rolling bench in a

workshop.

– Towing the vehicle.

– System initialization process after battery

disconnection.

– Sun or lights shining into the front camera

lens.

– Adverse environmental conditions (e.g. rain,

fog or snow).

– Vehicle ahead creating road spray.

The system performance may be affected by:

– Vehicle stability system in progress.

– Vehicle battery voltage out of range.

– Wet road reflecting lights.

– Close vehicles ahead.

– Tractors, muddy vehicles or vehicles with a

trailer.

– Banked roads.

As soon as the system detects a

potential collision, it prepares the

braking circuit. This may cause a slight noise

and a slight sensation of deceleration.

– Following a damage of the windscreen close

to the detection camera.

Operating conditions and

limits

The system is automatically

deactivated once the use of a different

diameter "space-saver" type spare wheel is

detected, or if a fault with the right or left

brake lamp is detected.

Following a severe crash (e.g. with airbag

deployment), the system is automatically

deactivated.

Vehicle moving forward without trailer.

Brake system operational.

ASR system activated.

Seat belts fastened for driver and front

passenger.

Stabilised speed on roads with no or low

curvature.

– Winding or hilly roads.

– Poor lighting conditions.

– Sudden lighting changes.

– Vehicle modifications (e.g. tyres).

This warning lamp lights up on the

instrument panel without any additional

message, to indicate that the automatic braking

system is not available.

This is a normal behavior indicating that a

condition is not fulfilled and which does not

request the support of a workshop.

In any situations with ignition on where

automatic braking presents a risk, deactivating

Have it checked by a CITROËN dealer or a

qualified workshop.

In case the detection is degraded or

temporarily unavailable by

environment conditions, then a driver

indication is not displayed (because a driver

action is not requested).

The system performance may be degraded or

not available by:

– Sensor covered with snow, ice, slush, mud or

dirt.

– Windscreen damaged or smeared, with

blurred view or covered with foreign items

(e.g. stickers).

It can be dangerous to drive if the

brake lamps are not in perfect working

order.

Driving

The driver must not overload the

vehicle (keep within the GVW limit and

load height limits for roof bars).

(orange)

Active Safety Brake

Visual and audible alert, warning that the

preceding vehicle is very close.

The message "Obstacle close" is displayed.

It is possible that collision warnings

are not given, are given too late or

seem unjustified.

The driver must always stay in control of the

vehicle and be prepared to react at any time

to avoid an accident.

Collision Risk Alert

This function warns the driver if there is a risk

of collision with the preceding vehicle, or with a

pedestrian or cyclist.

Modifying the alert trigger threshold

The trigger threshold determines the sensitivity

with which the function warns of the risk of

collision.

The selected threshold is memorised when the

ignition is switched off.

The threshold is set via the instrument panel

menu, using the steering-mounted controls.

Intelligent emergency

braking assistance (iEBA)

This function increases vehicle deceleration

if the driver does not brake enough to avoid a

collision.

This assistance is only provided if the driver

presses the brake pedal.

This function, also called "automatic emergency

braking", intervenes after the acoustic alert if

the driver does not operate the brake pedal

quickly enough.

The system aims at reducing the speed of

impact or avoiding a collision if the driver fails

to react.

Operation

Depending on the collision risk detected by the

system, an alert may be triggered and displayed

on the instrument panel.

The system takes into account the vehicle

dynamics, the difference speed of the own

vehicle and the object identified for the

collision risk, and the operation of the vehicle

(e.g. actions on the pedals, steering wheel) to

trigger the alert at the most relevant moment.

With LCD instrument panel

Below a speed of 30 mph (50 km/h),

automatic emergency braking may

slow down the vehicle to a complete stop.

Automatic emergency braking may reduce

the speed by a maximum of 30 mph

(50 km/h) speed.

Visual and audible alert, warning that a

collision is imminent.

Driving

Operation

The system operates subject to the following

conditions:

– At reduced speed in an urban environment,

when a stationary vehicle, pedestrian or cyclist

is detected.

– The vehicle's speed is between 6 mph and

84 mph (10 km/h and 135 km/h) when a moving

vehicle is detected.

This warning lamp flashes during the

intervention as soon as the function

applies the vehicle’s brakes.

During the flashing time, the function is not

available.

With an automatic gearbox or drive selector,

in the event of automatic emergency braking,

keep the brake pedal depressed, also after

a complete stop is reached, to prevent the

vehicle from rolling away.

With a manual gearbox, in the event of

automatic emergency braking bringing the

vehicle to a complete stop, the engine may

stall.

The brake pedal may feel hard and

vibrate slightly while the function is

operating.

If the vehicle comes to a complete stop,

automatic braking is maintained for 1 to

2 seconds.

The system is operational again after the

detection field has been cleaned.

In the event of a malfunction, this

warning lamp lights up on the

instrument panel, accompanied by the display

of a message and an audible signal.

Have it checked by a CITROËN dealer or a

qualified workshop.

If this warning lamp comes on after the

engine has been switched off and then

restarted, contact a CITROËN dealer or a

qualified workshop to have the system checked.

These warning lamps light up on

Deactivation/Activation

By default, the system is automatically

activated at every engine start.

The settings are changed via the instrument

panel menu, using the steering-mounted

controls.

Deactivation of the system is signalled

by the illumination of this warning lamp,

accompanied by the display of a message.

the instrument panel and/or in

the warning lamp display for seat belts and

front passenger airbag to indicate that the

driver's and/or front passenger's seat belt is not

fastened (depending on version). The automatic

braking system is deactivated until the seat

belts are fastened.

The system cannot be deactivated

above 10 km/h.

Malfunction

Distraction detection

For more information, refer to the

General recommendations on the use

of driving and manoeuvring aids.

This warning lamp lights up on the

instrument panel with the message

"Driving Assistance Sensor blind: Clean

sensor" if the sensor is masked.

The driver can override the automatic

emergency braking at any time by

strongly turning the steering wheel (evasive

manoeuver) and/or by firmly pressing the

accelerator pedal.

This is a normal behavior, which does not

request the support of a qualified workshop.

In this case, stop the vehicle and verify if the

front camera or the front radar is covered by

dirt, mud, sand, snow, ice or anything preventing

the sensing.

The function comprises the "Driver Attention

Warning" system.
